What to Do When the Mechanical Lock Won't Open the Car Door?

[RichardRose]

One reason the mechanical lock won't open the door is due to "disengagement," which renders the mechanical key ineffective. Additionally, some car models, when in anti-theft lock mode, not only lock the engine but also prevent the mechanical key from opening the door. Here are explanations for why the mechanical lock might not open the door: 1. Generally, the door lock mechanism of a car's central locking system uses a mechanical latch to secure the door. If the door lock isn't engaged, the external door handle or the interior door handle can open the door. 2. To open the door from the inside, if equipped with a lock switch, first activate it, then pull the interior handle, or pull the interior handle twice consecutively. 3. From a mechanical perspective, the interior and exterior handles each have their own rods or cables to open the door. Even if the vehicle loses power, the door can still be opened from the inside using the handle. 4. If none of these scenarios apply and the vehicle has an interior unlock button, you'll need to enter the car, start the ignition, and press the interior unlock button to release the lock.
